biomass co-firing with lignite represents an attractive solution for operating lignite-fired thermalpower plants (tpp) with the dual advantage of using local renewable resources and simultaneously reducingemissions. the subject of this study is technical and environmental investigation of the feasibility of the cofiring of soma lignite with some dried agricultural residues in the soma thermal p...

we introduce the notions of t-dual rickart and strongly t-dual rickart modules. we provide several characterizations and investigate properties of each of these concepts. it is shown that every free (resp. finitely generated free) $r$-module is t-dual rickart if and only if $overline{z}^2(r)$ is a  direct summand of $r$ and end$(overline{z}^2(r))$ is a semisimple (resp. regular) ring. it is sho...

The dual-fuel diesel engine (D.F.D.E) is a conventional diesel engine in which much of the energy released, hence power, comes from the combustion of gaseous fuel such as natural gas. The exhaust emission characteristics of the D.F.D.E needs further refinements, particularly in terms of reduction of Unburnt Hydrocarbons (U7HC) and Carbon Monoxide (CO) emission, because the concentration of thes...

The work presented in this paper is an attempt to evaluate the exhaust emission characteristics of a hydrogen-ethanol dual fuel combination with different percents of hydrogen substitutions (i.e. 0-80 % by volume and of 20 % increment ) at three different compression ratios of 7:1, 9:1 and 11:1. Experimental investigations have been carried out on a computer interfaced with; four-stroke cycle, ...

Microbial fuel cell represents an emerging technology to attain electrical energy from wastewater. There are several alternative methods available for wastewater treatment; Microbial fuel cell is one of them, which generates green energy from wastewater for making a contribution to renewable sources of energy. This study states the performance of microbial fuel cell with different parameters i....

A key component of a Solid Oxide Fuel Cell (SOFC) is the interconnect, which connects individual fuel cells in series to form cell stack reach desired electrical potential. The interconnect exposed air and parallel, these so-called dual-atmosphere conditions give rise especially severe corrosion on air-side. This work investigates coatings mitigate this effect. Physical Vapour Deposition (PVD) ...

Cylinder-to-cylinder combustion dispersion in internal engines might be caused by various factors (e.g. manufacturing variations of the injectors or nozzle coking) which can result an increase pollutant emissions. When dealing with low temperature concepts such as premixed dual-fuel, system suffer from additional source due to port fuel injection distribution. Conventional cylinder concentratio...

Dual fuel combustion leverages a high-reactivity (HRF) to ignite premixed low reactivity (LRF)–air mixture achieve high efficiencies and engine-out emissions. The difference in the relative amounts of these fuels in-cylinder stratification profoundly impacts dual combustion. effect increasing LRF energy substitution on at various fixed HRF (diesel) quantities was experimentally studied for two ...
